How to change the port OS

The port operating system is the device family your traffic appears to come from: iOS, macOS, Android, Windows 10, or Windows 11. You can set it once at purchase and change it at any time — without reconnecting.

The setting is only available for private ports. Multiport does not have this setting — the IP changes with every request; see Private port vs multiport (backconnect).

Choosing the OS at purchase

The easiest way is to set it right in the checkout:

1. Open the pricing page and press “Select” on the plan you need.
2. In the checkout window, find the “Port Operating System” block.
3. Pick a value from the list — “OS not selected” is the default.
4. Complete the purchase — the selected OS will be applied to every port of the order.

Changing the OS in the dashboard

You can change the OS at any moment after the purchase — the setting applies to each port separately:

1. Open the Dashboard — the “MY PROXIES” list.
2. Click the proxy row (or the “Manage” button).
3. Go to the “Settings” tab.
4. In the “Port Operating System” block, choose the value — “Default” or a specific OS — and press “Apply”.

The value is also visible right in the proxy list: the badge next to the row shows the current choice (“OS: iOS” etc.) and opens the settings on click.

The change applies immediately, without changing the IP or the connection credentials.

How to check the current value

The current OS is visible in two places:

• The proxy list — the badge next to the port name: “OS: macOS” or “OS not selected”;
• The side panel — the “Settings” tab, the “Port Operating System” block.

Via the API, the OS is set when creating a subscription: the os parameter of the op=purchase request (values ios, macos, android, win10, win11). See the API documentation for details.
